Part of having the great QB is acquiring them.
Polian got Kelly to sign. Kelly certainly didn't have to and, with the cache he had coming out of the USFL, could have forced the Bills to move him if he wanted to.
Gallagher made a shrewd waiver claim to get Kemp from the Chargers for essentially nothing. He also acquired Daryle Lamonica, it was the bonehead that followed him who traded Lamonica to the Raiders for nothing. That's 2 great QBs on Gallagher's + column (in a time when QBs were gold and being chased by 2 leagues)
Part of Butler's big problem was that he couldn't bring in a QB to follow Jim. Todd Collins, Alex Van Pelt, Rob Johnson, Doug Flutie. Collins was a #2, Johnson cost us a top 10 pick that could have been used on a myriad of players including Fred Taylor, Keith Brooking, Takeo Spikes, Randy Moss, and Tra Thomas.
